How we work in Brentwood
Assess
We work out how many people use each space and the fresh-air rate needed.
Design
Fan, duct and grille sizes are designed for air flow, noise and energy use.
Install
Ductwork and fans are installed and connected to controls. We keep work areas in Brentwood screened and tidy at the end of each day.
Balance
Air flows are measured and balanced to the design.
What to think about in Brentwood
Heat recovery
Bringing in cold air in winter costs energy. Heat recovery units reclaim much of it.
Shared buildings
In multi-let buildings, roof space, risers and plant areas are often controlled by a managing agent. We work to their permits and method-statement requirements.
Building Regulations
New or altered ventilation in England must meet Approved Document F. We design to it and hand over the commissioning records.
Leased premises
If your Brentwood premises are leased, the landlord's written consent is usually needed for external units, wall penetrations and roof access. We provide drawings and data sheets for the request.
Typical premises in Brentwood
- Pubs and bars: cooling for busy bars, function rooms and cellars, sited with neighbours in mind.
- Restaurants and cafés: dining rooms that stay comfortable next to a hot kitchen and a busy service.
- Schools and education: classroom cooling, ventilation and IT room cooling, installed in the holidays.
- Offices: zoned cooling and heating for open-plan floors, meeting rooms and comms rooms.
Two rules matter for most businesses in England: GB F-gas rules (leak checks from 5 tonnes CO2e) and the periodic energy inspection for more than 12 kW of air conditioning.
